About TransModeler
TransModeler is a traffic simulation package applicable to a wide array of traffic planning and modeling tasks. TransModeler can simulate many kinds of road networks, including freeways and downtown areas, and can analyze wide-area multimodal networks. It can be used to model and visualize the behavior of traffic systems in a 2-dimensional or 3-dimensional GIS environment to illustrate and evaluate traffic flow dynamics, traffic signal and ITS operations, and overall network performance.
Like other Caliper Corporation products, TransModeler is a native GIS environment. TransModeler integrates with TransCAD, the travel demand forecasting software. TransModeler includes a proprietary BASIC-like programming language (Caliper Script) within a development interface (GISDK) that allows automation of the TransModeler environment. TransModeler includes a relational database and a matrix engine for native matrix operations.
TransModeler simulates public transportation as well as bicycle, car, and truck traffic. Transit route system travel demand can be specified as either schedule or headway based. Pedestrian crossing demand can also be simulated.
TransModeler is inherently a trip-based simulation package. Demand can also be simulated using turning movement volumes. The trip-based routing handles a wide variety of intelligent transportation system (ITS) features such as managed lanes (such as HOV and HOT lanes), electronic toll collection, route guidance, and traffic detection and surveillance. Simulation-based dynamic traffic assignment (DTA) can be used to inform vehicle's route choices. Calibration methods like Origin-Destination Matrix Estimation (ODME) are also available.
TransModeler's road editor natively supports two-way links and roads, which enables automatic handling for two-way left-turn lanes (TWLTL) and automatic handling of overtaking/passing on two-lane highways. Vehicle conflict points and yield points are automatically calculated inside of intersections. Road networks can be imported from Synchro, CORSIM, and TransCAD line layers.
TransModeler includes various tools for managing a simulation project and the associated scenarios. Project databases, traffic signal timing plans, and other input data can be shared between multiple projects and scenarios.
